Description

A kind of device that can transmit gps data and speech simultaneously at the GSM net

The utility model belongs to the communications field, refers in particular to a kind of device that can transmit gps data and speech at the GSM net simultaneously.

At present, having multiple transmit simultaneously data and audio unit appearance on the market, mostly is to utilize the various device construction system, by wireless mode transmission information, and existing many real systems come into operation, but its function singleness, and its technical scheme also has many weak points.As: frequency efficiency is low, thereby causes power system capacity little; Transinformation content is few; Signal transmission distance is limited, is difficult to realize large-scale covering, when transmitting data and audio unit speech simultaneously, and communication robust difference etc.

The purpose of this utility model is to overcome the deficiency in the background technology and a kind of device that can transmit gps data and speech at the GSM net simultaneously is provided.

The purpose of this utility model is achieved in that and mainly includes housing, power supply, central processor unit, GSM antenna, RF processing unit, user's telecontrol antenna, GPS reception antenna, GPS processing unit, speech processing unit, it is characterized in that: the GPS processing unit is by GPS reception antenna receiving satellite signal, and handles and obtain locator data and deliver to central processor unit; RF processing unit receives and sends speech and short message data by the GSM antenna.

Wherein, described power supply processing circuit is respectively by power supply integrated chip IC1, C1, C2 and power supply integrated chip IC2, C3, C4 and triode Q1, Q2, R1 and constitute three road controllable electric powers;

Described GPS receiving element is made of receiving chip Igps.

Described central processor unit, by comprise central processing unit IC3, chip IC 4, program storage IC5, random data memory IC 6, communication control chip IC7, and the oscillating circuit that constitutes of the reset circuit that constitutes by R2, R3, C5 and C6, CR, C7 form.

Described RF processing unit Id10 is connected with communication control chip IC7 and speech processing unit IC12 respectively, to constitute sending and receiving short messages circuit and speech transmissions circuit.

The utility model receives gps signal by the GPS processing unit, to obtain the positional information of vehicle, convert the data format that can transmit on the GSM net short message channel to by central processing unit for processing, deliver to central processing unit after, send by RF processing unit; And speech information is obtained by speech processing unit IC12 (the vehicle-mounted handle of MOTORALA), also deliver to central processing unit after, send by RF processing unit.

Advantage of the present utility model is: the short message way by the GSM network transmits GPS locator data and control information, its long distance of signal transmission, and coverage is big; The frequency efficiency height; User capacity is big; Need not investment construction private wore network network, thereby reduce investment outlay; The operation and maintenance expense is low.The utility model organically combines together GPS location technology, gsm communication technology and GIS geographical information technology, and this makes the safety precaution of China's motor vehicle and scheduling rescue technological means that a new leap arranged.

Fig. 3 is a circuit diagram of the present utility model.

Below in conjunction with embodiment and Figure of description, the utility model is further described.

As shown in Figure 1 and Figure 2, operation principle of the present utility model is:

The utility model mainly includes housing 1, power supply 2, central processor unit 3, GSM antenna 4, RF processing unit 5, GPS reception antenna 8, GPS processing unit 9, speech processing unit 10, wherein GPS processing unit 9 is by GPS reception antenna 8 receiving satellite signals, and handles and obtain locator data and deliver to central processor unit 3; RF processing unit 5 receives or sends speech and short message data by GSM antenna 4; Speech processing unit 10 is connected with central processor unit 3.

As shown in Figure 3, physical circuit of the present utility model is:

Power supply processing unit 2, form three road controllable electric powers by IC1, C1, C2 and IC2, C3, C4 and Q1, Q2, R1 respectively, and three-way power can be respectively by CPU 3 controls, and deliver to each module respectively, wherein, IC1, IC2 are power supply integrated chip (7805), and Q1, Q2 are triode; GPS receives processing unit 9, is made of reception antenna 8 and receiving chip Igps, is used to handle the GPS received signal, and wherein, Igps is the GPS receiving processing module that MOTORALA produces, the TTL serial line interface with standard; Central processor unit 3, comprise central processing unit IC3 (87C51), chip IC 4 (74HC373), program storage IC5 (27C256), random data memory IC 6 (62C256), communication control chip IC7 (8251A/B), reach the reset circuit that constitutes by R2, R3, C5, the oscillating circuit that C6, CR, C7 constitute etc.; The module I d10 of RF processing unit 9 (the module I D10 of MOTORALA) is connected with the IC10 (the vehicle-mounted handle of MOTORALA) of communication control chip IC7 and speech processing unit 10 respectively, constitutes short message and speech and receives or transtation mission circuit.

The utility model receives gps signal by GPS processing unit 9, to obtain the positional information of vehicle, become the data format that can transmit on the GSM net short message channel by CPU 3 treatment conversion, send by RF processing unit 9, and speech information is obtained by the IC10 in the speech processing unit 10 (the vehicle-mounted handle of MOTORALA), after also delivering to central processing unit 3, also sent by RF processing unit 9, the speech information that the vehicle-mounted handle of the data message of GPS and MOTORALA is sent is simultaneously by the transmission of GSM net; After receive the reception base station of wireless office, the GPS information that is loaded on the short message channel is delivered to the short message machine, deliver to Surveillance center's decoding then, obtain information needed; Carry out exchange of speech in the switch and speech information delivered to, to corresponding called or caller.Reached the purpose that transmits gps data and speech at the GSM net simultaneously by inferior this.
